Jökulsárgljúfur Canyon in Iceland is 28 kilometres long and 100 metres deep in some places. Scientists at the University of Edinburgh have discovered the waterfall was formed in just a matter of days. They analyzed rocks along a five-kilometre stretch of the canyon – which contains the Jökulsá á Fjöllum River and the mighty Dettifoss waterfall – to create a timeline of how the landscape was created. The floods were caused by volcanic activity under the glaciers, forming the canyon’s 100-metre walls and pushing three waterfalls – including Dettifoss – back upstream by up to two kilometres each time.
